// the sake of testing. This functionality forms the back end for

// The Magical World of Goreland, is where Ted Stevens and Al Gore are from.
//
//
// It is composed of Big Trucks, and a Series of Tubes!
//
//
// Ok, it is basically just a Graph.
// Nodes are called "Trucks" and they have X, Y coordinates
// Edges are called "Tubes", they connect Trucks, and they have a cost
//
//
// The key differences between this example and the Tile world:
// 1) There is no grid. Trucks have arbitrary coordinates.
// 2) Edges are not implied by the grid positions. Instead edges are explicitly
// modelled as Tubes.
//
//
// The key similarities between this example and the Tile world:
// 1) They both use Manhattan distance as their heuristic
// 2) Both implement Pather
//Goreland represents a world of trucks and tubes.
